Flood Prevention Tips When Building A Home Next To A River

If you have recently purchased a piece of nice riverfront property and have been thinking about what type of house you are going to build, it is important to take the river into consideration. While the river might be calm and low now, you should take into account the times when it will be raging and perhaps even crest the banks and flood the land. You don't want your new home to be ruined because you built too close to the riverbank, or didn't take into account other flood precaution improvements. Here's a few to consider.

History Of Major Floods? Elevate House Plans

If you are building a house next to a river that has a history of large floods (you can check with the USGS or your new neighbors), then you might want to consider an elevated house plan. These homes are built with raised foundations (sometimes even incorporating support poles in lieu of raised concrete foundations). You will see these in coastal regions where there are frequent and large floods. If you are next to a small river, then this is not usually necessary, however if you are building next to a large river, or a tributary of a large river that gets overflow during flood times, then it is something to consider.

Minor Flooding Issues: French Drains Surrounding The House

If you don't have to worry about major, catastrophic flooding problems, then your new home is probably not the proper candidate for the elevated house plan. However, it is perfect for a french drain. These are underground drains that are built around your home that funnel water away from your homes foundation. The process involves digging large trenches around the perimeter and grading the trenches so that they are angled away from your home. Large pipes (normally pvc with holes drilled on the top to catch water) are laid in the trench alongside gravel. These trenches are then covered. The pipes collect the water and carry it away from your home.

These drains work great during a heavy storm when the area is being pounded by water. Instead of all of that rainwater flowing towards your foundation, it will be carried away. While it is best to have these trenches dug during the initial construction of the home, they can also be installed after the home is built. The reason it's best to have it done while the initial construction is being done is that the process of digging the trenches requires heavy machines (backhoes, etc.) and they can operate much more freely when they don't have to worry about driving over a septic tank or smashing into a porch.
